Abstract:
Objective To develop an overall health risk model and to evaluate its convergent validity and reliability.Methods Health examination results of 230 adults from a public institution were collected by using Chinese Health Risk Appraisal Questionnaire V1.0 (CHRAQ V1.0).An CHRAQ V1.0-based overall health risk model was then developed,which included 34 items.Kolmogorov-Smirnov was used to test normal distribution of the data.Pearson correlation coefficient and Spearman correlation coefficient were used to evaluate parallel validity of the model.Crane Bach coefficient,Spearman-Brown coefficient and test-retest reliability were calculated to evaluated the reliability of the model.Results In this study,212 valid questionnaires (92.17％) were received.The average score of the newly developed overall health risk model was 41.96 ± 9.69,and its kurtosis coefficient and coefficient of skewness were 2.105 and 0.862,respectively.In Kolmogorov-Smirnov,the data were normally distributed (Z =1.073,P =0.199).The correlation coefficient of positive rate of all objective examinations with model scores was 0.774 (P ＜ 0.05).The Cronbach's alpha coefficient,Spearman-Brown coefficient and test-retest reliability of the model were 0.652,0.784 and 0.841,respectively (P ＜ 0.05).Conclusion In this investigation,our newly developed overall health risk model shows good validity and reliability and application prospect in the field of health management.
